CVE-2025-23143

CVE-2025-23143 is a Linux kernel issue where unloading a module (e.g., CIFS/NFS) can race with a TCP socket still alive, leading to a NULL pointer dereference in lockdep when hlock_class() is called after the module is gone. The root cause is that CIFS assigns a different lock class to the socket...
